So I am trying to set-up a Portable-VitualBox on an external hard drive using a how-to-geek guide.

After extracting all files on the drive, when I run Virtual Box I get the following error:

Failed to create the VirtualBoxClient COM object.

The application will now terminate.

Callee RC: REGDB_E_CLASSNOTREG (0x80040154)

Anyone can help me finish setting this up ?

Could the error be becuz I had Oracle Virtual Box installed before on my system ? I uninstalled OVB before installing the Portabvle one on the external drive so unless some reg files were left behind or something, I really have no clue.

Thanks in advance
